Switching off DSC
Press the button; the indicator lamp in the
instrument cluster lights up continuously.
DSC is now deactivated.
Stabilizing interventions of the chassis control
system DSC are no longer available. However,
the braking interventions that simulate the
function of the differential lock continue to be
active.
In the following exceptional circumstances, it
may be useful to switch off DSC for a short
period:
>When rocking the vehicle and starting off in
deep snow or on loose road surfaces
>On sandy road surfaces
>On poor surfaces with deep ruts
>If the wheels spin on muddy surfaces
>When driving with snow chains
As a result of the braking interventions,
the brakes may be subjected to additional
loads when the system is switched off. In order
to limit the brake temperature, brief automatic
suppression of the brake activation is possible.
To maintain vehicle stability, always drive with
the system switched on when possible.<
Reactivating DSC
Press the button again; the indicator lamp in the
instrument cluster goes out. DSC is now acti-
vated.
xDrive
xDrive is the all-wheel drive system of your X3.
The combined effects of xDrive and DSC fur-
ther optimize the traction and dynamic driving
characteristics. The all-wheel drive system
xDrive variably distributes the drive torque to
the front and rear axle depending on the driving
situation and prevailing road conditions.
HDC Hill Descent Control
The concept
HDC is a system for hill descent assistance that
reduces the speed on steep downward inclines
and makes it even easier to control the driving
characteristics of your BMW under these condi-
tions. The vehicle moves at slightly more than
walking speed without active intervention from
the driver.
HDC is available for activation at vehicle speeds
below approx. 20 mph/35 km/h. When driving
down steep hills with a speed below approx.
20 mph/35 km/h, the vehicle reduces speed
automatically down to slightly more than walk-
ing speed, approx. 5 mph/8 km/h, and then
maintains this speed at a constant.
You can use the accelerator or brakes to vary
this automatically controlled speed within a
range extending from approx. 3 mph/5 km/h to
15 mph/25 km/h.
You can specify a target speed within the same
range by using the +/– buttons of the cruise
control on the steering wheel.

light-alloy wheels, different lug bolts may
also be required.
4.Screw in the remaining lug bolts. Tighten all
the bolts securely in a diagonal pattern.
5.Lower the jack and remove it from beneath
the vehicle.
After mounting
1.Tighten the lug bolts in a diagonal pattern.
To ensure safety, always have the lug
bolts checked with a calibrated
torque wrench as soon as possible to
ensure that they are tightened to the speci-
fied torque. The tightening torque is
101lbft/140Nm.<
2.Stow the defective wheel in the cargo area.
3.Check and correct the tire inflation pressure
at the earliest opportunity.
Protect valve stems and valve stem
seal caps against dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
4.Reinitialize the Flat Tire Monitor, refer to
page49.
Do not initialize the system when driv-
ing with the compact wheel.<
5.Replace the damaged tire with a new one as
soon as possible and have the new wheel
balanced.
Driving with compact wheel
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. Do not deacti-
vate DSC, as otherwise unstable driving condi-
tions may result.<
The driving characteristics change, for example
reduced track stability on braking, extended
braking distance, and altered self-steering
characteristics in the limit range. In conjunction
with winter tires, these characteristics are more
pronounced.
Only one compact wheel may be
mounted. You should re-equip with
wheels and tires of the original size as quickly as
possible.<
Vehicle battery
Maintenance
The battery is 100 % maintenance-free, i.e., the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate. Your BMW Sports Activity Vehicle Center
will be happy to consult you on all questions
concerning the battery.
Warning lamp
The warning lamp lights up. The bat-
tery is no longer being charged. The
alternator V-belt is defective or there is
a malfunction in the charge current circuit of the
alternator. Have the system checked immedi-
ately.
Do not continue driving if the V-belt is
defective. The engine could be damaged
due to overheating.
Moreover, an increased amount of force is
required for steering if there is a sharp drop in
the onboard supply voltage.<
Charging battery
Charge the battery in the vehicle only when the
engine is not running. Use the connections pro-
vided in the engine compartment. For connec-
tions, refer to Jump starting on page104.
Disposal
Have old batteries disposed of following
replacement at your BMW Sports Activity
Vehicle Center or bring them to a collection
point. Maintain the battery in an upright position
for transport and storage. Always secure the
battery to prevent it from tipping over during
transport.<
